* UBIFS: allow mounting when short of spaceArtem Bityutskiy2008-12-31
| | | | | | | | It is fine if there is not free space - we should still allow mounting this FS. This patch relaxes the free space requirements and adds info dumps. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix writing uncompressed filesArtem Bityutskiy2008-12-31
| | | | | | | | | UBIFS does not disable compression if ui->flags is non-zero, e.g. if the file has "sync" flag. This is because of the typo which is fixed by this patch. The patch also adds a couple of useful debugging prints. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix checkpatch.pl warningsArtem Bityutskiy2008-12-31
| | | | | | | | | | | | | | | | | These are mostly long lines and wrong indentation warning fixes. But also there are two volatile variables and checkpatch.pl complains about them: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gc_seq; WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gced_lnum; Well, we anyway use smp_wmb() for c->gc_seq and c->gced_lnum, so these 'volatile' modifiers can be just dropped.

* UBIFS: simplify make_free_spaceArtem Bityutskiy2008-12-31
| | | | | | | | The 'make_free_space()' function was too complex and this patch simplifies it. It also fixes a bug - the freespace test failed straight away on UBI volumes with 512 bytes LEB size. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: do not lie about used blocksArtem Bityutskiy2008-12-31
| | | | | | | | | | Do not force UBIFS return 0 used space when it is empty. It leads to a situation when creating any file immediately produces tens of used blocks, which looks very weird. It is better to be honest and say that some blocks are used even if the FS is empty. And ext2 does the same. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: restore budg_uncommitted_idxArtem Bityutskiy2008-12-31
| | | | | | | | | UBIFS stores uncommitted index size in c->budg_uncommitted_idx, and this affect budgeting calculations. When mounting and replaying, this variable is not updated, so we may end up with "over-budgeting". This patch fixes the issue. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: always commit on unmountArtem Bityutskiy2008-12-31
| | | | | | | | | | | | | UBIFS commits on unmount to make the next mount faster. Currently, it commits only if there is more than LEB size bytes in the journal. This is not very good, because journal size may be large (512KiB). And there may be few deletions in the journal which do not take much journal space, but which do introduce a lot of TNC changes and make mount slow. Thus, jurt remove this condition and always commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: use ubi_syncArtem Bityutskiy2008-12-31
| | | | | | | UBI now has (fake for now, though) synchronization call - use it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: always commit in sync_fsArtem Bityutskiy2008-12-31
| | | | | | | | | | Always run commit in sync_fs, because even if the journal seems to be almost empty, there may be a deletion which removes a large file, which affects the index greatly. And because we want better free space predictions after 'sync_fs()', we have to commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix file-system synchronizationArtem Bityutskiy2008-12-31
| | | | | | | | | | Argh. The ->sync_fs call is called _before_ all inodes are flushed. This means we first sync write buffers and commit, then all inodes are synced, and we end up with unflushed write buffers! Fix this by forcing synching all indoes from 'ubifs_sync_fs()'.

* UBIFS: fix constants initializationArtem Bityutskiy2008-12-31
| | | | | | | | | The c->min_idx_lebs constant depends on c->old_idx_sz, which is read from the master node. This means that we have to initialize c->min_idx_lebs only after we have read the master node. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| | | | | | | | When we commit, but before we try to write anything to the flash media, @c->min_idx_size is inaccurate, because we do not re-calculate it after the commit. Do not forget to do this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBIFS: fix available blocks countArtem Bityutskiy2008-12-23
| | | | | | | | | | Take into account that 2 eraseblocks are never available because they are reserved for the index. This gives more realistic count of FS blocks. To avoid future confusions like this, introduce a constant. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| * [WATCHDOG] hpwdt: Fix kdump when using hpwdtBernhard Walle2008-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the "hpwdt" module is loaded (even if the /dev/watchdog device is not opened), then kdump does not work. The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

| * | UBIFS: pre-allocate bulk-read bufferArtem Bityutskiy2008-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid memory allocation failure during bulk-read, pre-allocate a bulk-read buffer, so that if there is only one bulk-reader at a time, it would just use the pre-allocated buffer and would not do any memory allocation. However, if there are more than 1 bulk- reader, then only one reader would use the pre-allocated buffer, while the other reader would allocate the buffer for itself.

| * | UBIFS: do not allocate too muchArtem Bityutskiy2008-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bulk-read allocates 128KiB or more using kmalloc. The allocation starts failing often when the memory gets fragmented. UBIFS still works fine in this case, because it falls-back to standard (non-optimized) read method, though. This patch teaches bulk-read to allocate exactly the amount of memory it needs, instead of allocating 128KiB every time. This patch is also a preparation to the further fix where we'll have a pre-allocated bulk-read buffer as well. For example, now the @bu object is prepared in 'ubifs_bulk_read()', so we could path either pre-allocated or allocated information to 'ubifs_do_bulk_read()' later. Or teaching 'ubifs_do_bulk_read()' not to allocate 'bu->buf' if it is already there. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBIFS: do not print scary memory allocation warningsArtem Bityutskiy2008-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bulk-read allocates a lot of memory with 'kmalloc()', and when it is/gets fragmented 'kmalloc()' fails with a scarry warning. But because bulk-read is just an optimization, UBIFS keeps working fine. Supress the warning by passing __GFP_NOWARN option to 'kmalloc()'. This patch also introduces a macro for the magic 128KiB constant. This is just neater. Note, this is not really fixes the problem we had, but just hides the warnings. The further patches fix the problem. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBIFS: allow for gaps when dirtying the LPTAdrian Hunter2008-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LPT may have gaps in it because initially empty LEBs are not added by mkfs.ubifs - because it does not know how many there are. Then UBIFS allocates empty LEBs in the reverse order that they are discovered i.e. they are added to, and removed from, the front of a list. That creates a gap in the middle of the LPT. The function dirtying the LPT tree (for the purpose of small model garbage collection) assumed that a gap could only occur at the very end of the LPT and stopped dirtying prematurely, which in turn resulted in the LPT running out of space - something that is designed to be impossible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the "UBIFS background thread ubifs_bgd0_0 started" message. We kill the background thread when we switch to R/O mode, and start it again whan we switch to R/W mode. OLPC is doing this many times during boot, and we see this message many times as well, which is irritating. So just kill the message. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| * | | KVM: MMU: avoid creation of unreachable pages in the shadowMarcelo Tosatti2008-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for a shadow page to have a parent link pointing to a freed page. When zapping a high level table, kvm_mmu_page_unlink_children fails to remove the parent_pte link. For that to happen, the child must be unreachable via the shadow tree, which can happen in shadow_walk_entry if the guest pte was modified in between walk() and fetch(). Remove the parent pte reference in such case. Possible cause for oops in bug #2217430. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the VM exits, we must call put_page() for every page referenced in the shadow TLB. Without this patch, we usually leak 30-50 host pages (120 - 200 KiB with 4 KiB pages). The maximum number of pages leaked is the size of our shadow TLB, 64 pages.
